WFS fail to connect to http://demo.opengeo.org/geoserver/wfs?service=wfs

Reported by Autodesk QA: cannot connect to ​http://demo.opengeo.org/geoserver/wfs?service=wfs.

This is because the URL contains "service=wfs" already. FDO WFS provider tries to add it again, for example request ​http://demo.opengeo.org/geoserver/wfs?service=wfs&version=1.0.0&'''service=WFS'''&REQUEST=GetCapabilities, it fails:

<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0.0" xsi:schemaLocation="http://www.opengis.net/ows http://demo.opengeo.org:80/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd">
<ows:Exception exceptionCode="InvalidParameterValue" locator="service">
<ows:ExceptionText>
Single value expected for request parameter service but instead found: [wfs, WFS]
</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

Also need to pay attention to its request=<DescribeFeatureType or GetFeature>, because the URL already contains.

• ​http://demo.opengeo.org:80/geoserver/wfs?request=DescribeFeatureType
• ​http://demo.opengeo.org:80/geoserver/wfs?request=GetFeature

This defect is caused by the WFS URL contains "service=wfs" already. Previously FDO WFS provider always add version=<version>&service=WFS&REQUEST=GetCapabilities to request, so make it:

http://demo.opengeo.org/geoserver/wfs?service=wfs&version=1.0.0&service=WFS&REQUEST=GetCapabilities

and this URL returns error:

<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0.0" xsi:schemaLocation="http://www.opengis.net/ows http://demo.opengeo.org:80/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd">
<ows:Exception exceptionCode="InvalidParameterValue" locator="service">
<ows:ExceptionText>
Single value expected for request parameter service but instead found: [wfs, WFS]
</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

Fix is to compare URL, if it already contains "service=WFS" (case insensitive), FDO WFS provider not add duplicate parameter again.

The same problem also happen when do DescribeFeatureType and GetFeature, as this WFS's url contains "request=..." already.

http://demo.opengeo.org:80/geoserver/wfs?request=DescribeFeatureType
http://demo.opengeo.org:80/geoserver/wfs?request=GetFeature
